From the foregoing the advantages of my As the parent application above referred to improved structure will be readily understood. 5 fully discloses the broad features of this in- Heretofore walk-over car-seats have been vention and the seat and back supporting provided with a-plurality of supporting-links 4 mechanism whereby the back is supported by "at each end similar to the links shown in Fig. a single link at one end and a plurality of links 1. 7 By examining said figure it is obvious that at the other, it is unnecessary in this case to the ends of the links 8 which are pivoted to 9 fully describe and illustrate such a structure, the T-iron 18 at the end of the back are pivoted and so this case will be restricted to the parout of the plane of the back, so that the links 45 ticular improvement with which it relates. are in a plane or surface perpendicular to the The seat l-is supported at one end by any plane of the back and are parallel to each other suitable support, such as legs 2, and at the and separated in a seat of the usual size by a other end by a panel 3, which rests against l distance of several inches. This structure from its nature cannot be compact and necessarily occupies a great deal of space. In the structure shown in Fig. 2 of this application it is obvious that the single link 11 is pivoted at its upper end 19 in the plane of the back 7, so that a very compact structure is formed and the link 11 can operate close to the panel 8, whereby valuable seating-space is saved in the car. This result would be impossible if two links were employed at the end next the seat-panel. \Vhile this form of seat is applicable for many purposes, it is particularly adapted for use in convertible cars where it is necessary to have a center aisle for winter use and easy access to the seats between the stanchions when the car is open for summer use, because the requirements are such that the back-supporting links should not extend a material distance above the cushion so as to interfere with the center aisle, yet they must always hold the back so as to be readily reversed.

In view of the above it is obvious that the essence of the invention in this case is in providing a seat supported at one end close to the panel and having one end of the back supported by a single link which moves between the end of the seat and the panel when the seat is reversed, and while I have shown and described only one structure for accomplishing this result all others employing this idea come within the scope of my invention.

What I claim is- 1. In a car-seat or similar device, a seat with a curved end, a curved panel adjacent to said end, a back, a single link supporting one end of said back, and adapted to move between said end and panel when the seat is reversed, and means for supporting the other end of said back.

2. In a car-seat or similar device, a curved panel, a seat provided with a curved end situated adjacent to said panel, stops separating said seat and panel, a back, a link supporting one end of said back and pivoted so as to move between the end of said seat and panel when the seat is reversed, and rest on one or the other of said. stops at the limit of its movement, and means for supporting the other end of said back.

3. In a car-seat or similar device, a curved panel supporting one end of said seat, a single link pivoted so as to move between said panel and curved ends of said seat, a' back supported at one end by said curved link and means for supporting the other end of said back.

4. In a car-seat or similar device, a curved panel, a seat with a curved end, a bracket with stops fixed to said seat and panel, a single link pivotally supported by said bracket, a back pivotally supported by said link, and means for supporting the other end of said back.

5. As an article of manufacture, a bracket for pivotally supporting a link which comprises a single horizontal web and offset vertically-disposed webs terminating so as to form stops which are adapted to limit the movement of a link.
